How long does it take to build an app?

The honest short answer to how long does it take to build an app is: a base MVP takes roughly 1.5 to 3 months, and a full enterprise build attempted in one go is closer to 5 to 6 months. Everything in between depends on the idea. That is the range we actually work to, not a marketing number, and this guide breaks down where every one of those weeks goes.

We are Zarle Infotech, a Noida team that has shipped apps like Chefadora, Fit Mom by Pooja Batra, and Optima Learning. So when we answer how long does it take to build an app, we are answering from finished projects, not a template. Most estimates you find online are wide on purpose so nobody can hold the agency to them. Ours are tighter because we have built these apps and watched the clock.

The real answer: timelines by app level

There is no single number for how long does it take to build an app, because a to-do app and a hospital booking platform are not the same job. What helps is a range per level of scope. Here is how we split it.

A base MVP, meaning one core workflow built properly, runs about 1.5 to 3 months. A mid-level MVP with a bit more in it lands closer to 1 to 1.5 months when it is tight, stretching to 2.5 or 3 months as features get added. A full enterprise build done in a single push is roughly 5 to 6 months. Bigger idea, longer clock. That is the whole rule.

If you compare those to the wider industry ranges, the shape is the same. Most guides put a simple app at 2 to 3 months, a medium app at 4 to 6, and a complex or compliance-heavy build at 9 to 12 months or more. We land at the faster end of those bands for one concrete reason we will get to: we build cross-platform by default, which is 30 to 40 percent faster than shipping two separate native apps. For more on that choice, see our cross-platform app development guide.

Where the weeks actually go: the phases

To understand how long does it take to build an app, you have to see the phases, because the calendar time is spread across five of them and they do not all run one after another.

Ideation and scoping. Before design, we pin down who the app is for and the one problem it solves. This is short in calendar terms, often a week or two, but it decides everything downstream. Skip it and the build takes longer, because you end up redoing work. This is also where we draw the v1 line, which is the single biggest lever on the timeline.

Design. Wireframes then UI, usually 2 to 4 weeks for an MVP depending on how many screens the core workflow needs. Design and early development often overlap once the key screens are signed off.

Development. The longest phase, and where the MVP versus enterprise gap really shows. For a base MVP this is a few weeks of a single developer building one codebase for both platforms. We default to React Native because our websites run on React and Next.js, so we reuse the same TypeScript and patterns and move faster. One developer building cross-platform ships at close to double the speed of two native developers writing every feature twice.

Testing and iteration. Not a phase you bolt on at the end. It runs alongside development, and it is where quality gets earned. We build and test on both iOS and Android from the start, because the two render differently and you want to catch that early, not in launch week.

Store approval. The phase founders forget entirely, and it can quietly add a couple of weeks if you leave it late. More on that below, because it is the most avoidable delay in the whole timeline.

Here is the part that matters. Every feature runs its own full cycle: ideation, design, development, output, then testing and iteration. So "one more feature" is never just coding time. It is a whole small loop. That is why the answer to how long does it take to build an app is really a question about how many of those loops you are signing up for.

Why app projects slip past their deadline

Ask any founder who has been through a build and they will tell you the estimate rarely holds. Here is the real reason, and it is not lazy developers.

Scope does not balloon at the start. It balloons in the middle. A founder watches the app take shape, gets ten or fifteen new ideas mid-build, and each one runs that full cycle of design, development, and testing. A feature scoped for two weeks quietly becomes three or four, and it compounds across the project. That is genuinely how most apps slip past their deadline. The ideas are usually good. They are just v2 ideas arriving during v1.

This is why we do not work to a hard, fixed deadline that everyone then quietly breaks. We work on the product daily to make it better, against a rough estimated timeline both sides agree on. If we go past it, both sides know exactly why: we were actively improving a design or a feature, not drifting. The cure for slippage is phased planning. Lock the v1 scope, write down every later idea so none are lost, and ship the small version first. We go deeper on scoping in our mobile app MVP guide.

A worked example makes it concrete. For an ecommerce app, founders reliably want the whole store on day one. The entire value, though, is that a person finds a product and buys it. So v1 is two things: a product page and a checkout. Recommendations, collections, multiple logins, multiple payment options, wishlists, and reviews are all real and all later. Build up in phases and the first version ships in weeks instead of months.

Get your app approved early, not at the end

The most avoidable delay in any app timeline is store approval, and it hits when founders treat the developer accounts as a launch-week formality. They are not. Sort them out before you build.

The biggest trap is rushing to create your store accounts as an individual. Apple lets you switch from individual to organization, but that switch takes around three to four weeks. Google Play gives you no switch at all, so you would have to create a brand new account and re-register from scratch. So set up the organization first: register the business properly, get your DUNS number, and only then create the Apple and Google accounts. Even solo founders are better off with a sole proprietorship or an LLC than an individual registration.

Individual accounts also drag out testing. On an individual Google account you need 12 testers actively testing for 14 days before you can push to production. An organization account can go to production from day zero. That single choice can add or save two weeks near the finish line. We laid out the full comparison in our individual versus organization developer account post.

Then there is the review itself. As of 2026, the App Store takes longer than it used to for a first submission, roughly 1 week to 10 days at the slow end, though most reviews land in 2 to 3 days, and updates come back in 24 to 48 hours. Google Play is faster, usually about 24 hours and at most 48 if something gets flagged. Get the MVP submitted for review as soon as it is ready, because approval time is outside your control and you do not want it on the critical path. We cover the specifics in App Store versus Play Store review time.

What makes the timeline shorter or longer

If you want to influence how long does it take to build an app for your specific idea, these are the levers that move the number most.

• Cross-platform versus native. For about 95 percent of ideas, cross-platform is the right call, and it is faster because one codebase serves both platforms. Only heavy-animation, hardware-dependent, or performance-critical apps in the remaining 5 percent need native, which means two developers and roughly double the build.
• Number of core features. Every feature is a full loop of design, build, and test. Three focused features ship far faster than ten half-considered ones.
• Backend complexity. Starting on a managed backend like Firebase is quicker than standing up custom infrastructure for an app that has no users yet. You migrate later if the bill or the requirements justify it.
• Integrations. Payments, maps, third-party APIs, and login providers each add build and test time. They are worth it when they serve the core workflow and a delay when they do not.
• Decision speed on your side. Fast feedback on designs and clear answers to scope questions keep the clock moving. Slow sign-offs are one of the quietest causes of a stretched timeline.

Launch both platforms together

One timing decision worth making early: launch iOS and Android at the same time rather than one and then the other. We build on both from the start anyway, because they render differently and you want to catch those differences during development, not after. In the Indian market the user base skews Android, so if you truly must lead with one platform, lead with Android. For an audience that skews Apple, flip it. But a simultaneous launch is almost always the better call, and it does not add much time when both builds have been running side by side the whole way.

What we will not do: quote a price off a timeline

A timeline is not a price. We will not put a single rupee figure on building an app in a blog post, because the cost genuinely depends on the idea, the number of developers, how long the build runs, and whether you need a backend. The knowable costs are the store fees: Apple charges around 99 dollars a year, recurring, and Google Play is a one-time 25 dollars. For the build itself, the right move is a proper conversation about your actual scope. If you want a real number, our mobile app development cost in India breakdown explains the drivers.

Frequently asked questions

How long does it take to build an app from scratch?

For a base MVP, roughly 1.5 to 3 months. A tight mid-level MVP can land in about 1 to 1.5 months, stretching to 2.5 or 3 months as you add features. A full enterprise build in one go is closer to 5 to 6 months. The exact figure depends on the idea, the number of features, and whether you need a custom backend.

Why do app projects take longer than the estimate?

Almost always because of scope creep in the middle of the build. Founders get new ideas as the app takes shape, and each new feature runs a full cycle of design, development, and testing. A two-week feature becomes three or four, and it compounds. Phased planning, where you lock v1 and defer the rest, is the fix.

How long does app store approval take in 2026?

The App Store is usually 2 to 3 days, though a first submission can take up to 10 days, and updates come back in 24 to 48 hours. Google Play is faster, about 24 hours and at most 48. Set up an organization developer account early so account issues do not delay you.

Can you build an app faster with cross-platform?

Yes. One cross-platform codebase serves both iOS and Android, so a single developer works at close to double the speed of two native developers. That is why cross-platform builds run 30 to 40 percent faster, and why we default to it for the roughly 95 percent of apps that do not need native.

Does a bigger team make the app ship faster?

Only up to a point. Beyond the core workflow, more developers add coordination overhead rather than speed. What reliably shortens the timeline is a tighter scope, fast decisions on your side, and getting the developer accounts and store approval sorted before they become a launch-week emergency.

How much of the timeline is actually the build?

Less than founders expect. The build is roughly 30 percent of getting an app to succeed. The rest is distribution, retention, and iteration after launch. So plan your calendar around the whole journey, not just the coding phase. We cover this in why mobile apps fail.

Ready to put a real timeline on your idea?

The honest answer to how long does it take to build an app is that it depends on scope, but the ranges are knowable: 1.5 to 3 months for a base MVP, up to 5 to 6 months for a full enterprise build. The fastest path is a tight v1, a cross-platform codebase, and store accounts sorted early.
